Verified step by step guidance
1
Understand the stages of mitosis: Mitosis is divided into several phases: prophase, metaphase, anaphase, and telophase.
Identify the role of the spindle apparatus: The spindle apparatus is responsible for separating chromosomes during mitosis.
Recall what happens during each phase: In prophase, the spindle fibers form. In metaphase, chromosomes align at the cell's equator. In anaphase, sister chromatids are pulled apart by the spindle fibers.
Focus on telophase: During telophase, the chromosomes arrive at opposite poles, and the spindle apparatus begins to disassemble.
Conclude that the spindle apparatus is broken down during telophase, as the cell prepares to complete division and enter cytokinesis.
